Car was build ~12 months ago, and is from North QLD, so don't imagine it would be particularly well known.

Yes, stock open diff... holding up fine so far... no grinding noises or anything! I have an R31 diff that I'm cutting down to go in shortly, just gotta finish my cooler mods & new piping first.

It was still wheelspinning a tiny bit even with the guys in the boot. The tyres on it are absolute junk, and the lack of an LSD doesn't help things.
